The numerical study of acoustical attenuation and velocity in the suspension of superfine particles

To research the particle measurement with ultrasonic, Allegra & Hawley model was introduced to study the acoustical propagation in suspensions. Based on two examples of TiO₂ - Water and Iron-Water suspension, the attenuation and phase velocity were analyzed. The influence of frequency, particle size and concentration was investigated in this paper. At the same time, the parameter sensitivity of this model was discussed.
